Mechanical performance of lightweight polycrystalline Ni nanotubes
(ELSEVIER SCIENCE BV, 2019)The mechanical properties of metallic nanowires and nanotubes were investigated using atomistic molecular dynamics simulations on Ni polycrystalline structures, similar to those experimentally obtained by Atomic Layer ... -
Comparative genomics identifies potential virulence factors in Clostridium tertium and C. paraputrificum
(TAYLOR & FRANCIS INC, 2019)Some well-known Clostridiales species such as Clostridium difficile and C. perfringens are agents of high impact diseases worldwide. Nevertheless, other foreseen Clostridiales species have recently emerged such as Clostridium ... -
Activating PTEN Tumor Suppressor Expression with the CRISPR/dCas9 System
(CELL PRESS, 2019)PTEN expression is lost in many cancers, and even small changes in PTEN activity affect susceptibility and prognosis in a range of highly aggressive malignancies, such as melanoma and triple-negative breast cancer (TNBC). ... -
Diapause induces functional axonal regeneration after necrotic insult in C. elegans
(PUBLIC LIBRARY SCIENCE, 2019)Many neurons are unable to regenerate after damage. The ability to regenerate after an insult depends on life stage, neuronal subtype, intrinsic and extrinsic factors. C. elegans is a powerful model to test the genetic and ... -
Country's International Reputation Index
(PALGRAVE MACMILLAN LTD, 2019)Nowadays it is very common to make decisions about our actions and behaviors based on a series of perceptions, which have been created according to a series of variables, and in many cases their deep knowledge is unnecessary. ... -
Pulsed radiofrequency of superior cervical ganglion for treatment of painful post-traumatic trigeminal neuropathy (PTTN): A case series report
(TAYLOR & FRANCIS LTD, 2019)Objective: Painful post-traumatic trigeminal neuropathy (PTTN) is a clinical pain syndrome that occurs due to injuries to the peripheral branches of the trigeminal nerve and is characterized by a deep burning pain and ... -
Finite mixture-of-gamma distributions: estimation, inference, and model-based clustering
(SPRINGER HEIDELBERG, 2019)Finite mixtures of (multivariate) Gaussian distributions have broad utility, including their usage for model-based clustering. There is increasing recognition of mixtures of asymmetric distributions as powerful alternatives ... -

High-fat diet induces mouse liver steatosis with a concomitant decline in energy metabolism: attenuation by eicosapentaenoic acid (EPA) or hydroxytyrosol (HT) supplementation and the additive effects upon EPA and HT co-administration
(ROYAL SOC CHEMISTRY, 2019)High-fat-diet (HFD) feeding is associated with liver oxidative stress (OS), n-3 long-chain polyunsaturated fatty acid (n-3 LCPUFA) depletion, hepatic steatosis and mitochondrial dysfunction. Our hypothesis is that the ... -
Simple approach for cleaning up 2,4,6-trichloroanisole from alcoholic-beverage-reconstituted solutions using polymeric materials
(WILEY, 2019)Background and Aims 2,4,6-Trichloroanisole (TCA) is a well-recognised contaminant in the wine and whisky industries. In this work, several polymeric materials were tested through a hybrid strategy (computational and ... -
Effect of human tubal fluid medium and hyperactivation inducers on stallion sperm capacitation and hyperactivation
(WILEY, 2019)Contents Conventional in vitro fertilization has not yet been implemented in the equine species. One of the main reasons has been the inability to develop a culture medium and incubation conditions supporting high levels ... -
Impact of post-thaw supplementation of semen extender with antioxidants on the quality and function variables of stallion spermatozoa
(ELSEVIER SCIENCE BV, 2019)During cryopreservation procedures, the spermatozoa are exposed to physical and chemical stressors that generate an increase in the intracellular concentration of reactive oxygen species (ROS). If ROS concentrations are ... -
In search of the most active MN4 catalyst for the oxygen reduction reaction. The case of perfluorinated Fe phthalocyanine
(ROYAL SOC CHEMISTRY, 2019)Iron macrocyclic complexes (MN4) are promising catalysts for replacing platinum (the industrial standard) in electrocatalysis. In particular, FeN4 complexes have shown lower overpotential than Pt for the oxygen reduction ... -
Differential source-sink manipulation affects leaf carbohydrate and photosynthesis of early- and late-harvest nectarine varieties
(BRAZILIAN SOC PLANT PHYSIOLOGY, 2019)Source-sink balance is a major determinant of carbon partitioning within plants. Thinning is an agronomic practice that consists of changing the ratio between leaves and fruits, the source and sink plant organs, respectively. ... -
Comparison of total hip arthroplasty surgical approaches by Statistical Parametric Mapping
(ELSEVIER SCI LTD, 2019)Background: The most common surgical approaches in use for total hip arthroplasty are the lateral and posterior. When comparing these approaches in terms of gait biomechanics, studies usually rely on pre-defined discrete ... -
First record of fossil procyonid (Mammalia, Carnivora) from Uruguay
(PERGAMON-ELSEVIER SCIENCE LTD, 2019)Procyonids were the first carnivorans that arrived from North America to South America during the late Miocene, before the full emergence of the Panama Isthmus. In South America, this family comprises five living genera ... -
